It is impossible to make anything
foolproof because fools are so ingenious.

If everything seems to be going well,
you have obviously overlooked something.

Left to themselves, things tend to go
from bad to worse.

Murphy's Law of Research:
Enough research will tend to support your theory.

Murphy's Law of Copiers:
The legibility of a copy is inversely proportional to its
importance.

Murphy's Law of the Open Road:
When there is a very long road upon which there is a one-way
bridge placed at random, and there are only two cars on that road,
it follows that: (1) the two cars are going in opposite
directions, and (2) they will always meet at the bridge.

Murphy's Law of Thermodynamics:
Things get worse under pressure.

Murphy's Constant:
Matter will be damaged in direct proportion to its value.

Rule of Accuracy:
When working toward the solution of a problem, it always helps if
you know the answer.

Anybody can win -- unless there
happens to be a second entry.

Airplane Law:
When the plane you are on is late, the plane you want to transfer
to is on time.

The theory is supported as long as
the funds are.

Nothing is as easy as it looks.

If there is a possibility of several
things going wrong, the one that will cause the most damage will
be the one to go wrong. Corollary: If there is a worse time for
something to go wrong, it will happen then.

If you perceive that there are four
possible ways in which a procedure can go wrong, and circumvent
these, then a fifth way, unprepared for, will promptly develop.

Nature always sides with the hidden
flaw.

Whenever you set out to do something,
something else must be done first.

Every solution breeds new problems.

Enough research will tend to support
your theory.

You cannot successfully determine
beforehand which side of the bread to butter.

The chance of the bread falling with
the buttered side down is directly proportional to the cost of the
carpet.

You never run out of things that can
go wrong.

Murphy's law of war:
No battle plan ever survives contact with the enemy.

Murphy's law of war:
Friendly fire ain't.

Murphy's law of war:
The most dangerous thing in the combat zone is an officer with a
map.

Murphy's law of war:
The buddy system is essential to your survival; it gives the enemy
somebody else to shoot at.

Murphy's law of war:
Incoming fire has the right of way.

Murphy's law of war:
If your advance is going well, you are walking into an ambush.

Murphy's law of war:
If you really need an officer in a hurry, take a nap.

Murphy's law of war:
The only thing more accurate than incoming enemy fire is incoming
friendly fire.

Murphy's law of war:
There is nothing more satisfying that having someone take a shot
at you, and miss.

Murphy's law of war:
If your sergeant can see you, so can the enemy.

After you have divided people into
even groups, someone will walk in late making it impossible to
redivide them into even groups.

In the first few miles of any long
road trip a large bug will accidentally attach itself to your
windshield in the driver's line of sight.

You can never tell which way the
train went by looking at the track.

Murphy's law of technology:
If builders built buildings the way programmers wrote programs,
then the first woodpecker that came along would destroy
civilization.

Murphy's law of technology:
The attention span of a computer is only as long as it electrical
cord.

Murphy's law of technology:
All great discoveries are made by mistake.

Nothing ever gets built on schedule
or within budget.

A meeting is an event at which the
minutes are kept and the hours are lost.

A failure will not appear till a unit
has passed final inspection.

New systems generate new problems.

Murphy's law of technology:
Any given program, when running, is obsolete.

Murphy's law of technology:
A computer makes as many mistakes in two seconds as 20 men working
20 years make.

The primary function of the design
engineer is to make things difficult for the fabricator and
impossible for the serviceman.

Murphy's law of technology:
Any circuit design must contain at least one part which is
obsolete, two parts which are unobtainable and three parts which
are still under development.

If mathematically you end up with the
incorrect answer, try multiplying by the page number.

If you can't understand it, it is
intuitively obvious.

If it's not in the computer, it
doesn't exist.

If an experiment works, something has
gone wrong.

When all else fails, read the
instructions.

Any instrument when dropped will roll
into the least accessible corner.
